Does parallax effect target image?

This sight has a wealth of information about parallax but I can't find an answer to my question.

 

I have a 3X12X42 scope that's doesn't have the AO feature. (It's not a "cheap" scope.)The reticle is in perfect focus and very clear.

 

Since it does not have an AO is it normal for the image of the actual target you're looking at be out of focus?

It's out of focus at all ranges but is worse at longer distances.

 

I've sent it to the mfg. to be checked but I'm still curious.

 

Thanks

Not normal.  My understanding is that most scopes up to about 12X don't have adjustable obj & are set to be parallax free to 100yds - this may vary & scope manufacturer can tell you what it is.  After about 12X most have an AO to precisely focus the target image on the reticle plane.

 

Your telling statement is "It's out of focus at all ranges", sounds like a factory alignment problem to me.

Actually it is more normal than thought--- and one of the reasons for so many "dirty" comments about Leo's glass. Whether the comments are warranted or not, I'm not going to get into. If the AO is set at infinity and the rear focus is set correctly, in most Leos, the cross hair and the target are never in focus to my eyes. Some others that have observed this suggest it may be a result of the difference between SFP and FFP scopes. It is not a problem with my shooting style because I don't watch the cross hair and push the shot off through the target as fast as possible. Target "settters" would have a problem and since most shooting is done of benchs and at targets rather than action shooting more comments would be expected.

AO is designed for focus problems at short distance, not long, unless I'm misreading your post, so your problem as dogger has suggested needs a factory look at.

Is this by any chance a Sightron SII?  One question I would have to ask before sending it back, do you wear reading glasses?  Given the lack of an AO and without a diopter adjustment on the eyepiece, if you are not wearing your reading glasses everything will appear blurry at all mags.  It is odd, but some scopes I use do not require me to do this, but others do.  I have this model with the AO and do not have to wear my reading glasses.  I remember I was hunting in a deer stand a couple years ago and a doe came out at about 125 yards.  I was hunting with a Howa 300 winmag. with a pre-Meade Simmons Aetec.  As I got ready to take aim, my future son in law said there was a buck 90 degrees to the doe.  I turned and the shot I had was a frontal.  I took a quick aim and everything was blurry.  I realized I did not have my reading glasses on.  The distance to the buck was about the same.  So I had to make a decision, take the blurry shot or try to find my reading glasses and make noise and lose the shot.  So, I took the blurry shot and got the deer.  Let us know.

Thanks for all the input.

It is a Sightron II and I do wear glasses with progressive lenses.

Since I don't have this problem with any of my other scopes I didn't consider that

as a factor.

I sent it to the mfg. for them to look at. From what I've heard the service is great.

We'll see how things go when I get it back.
